Latest Patents
Offringa's latest patents include a method for fabricating a permanent magnet rotor and a control circuit for a DC/three-phase current converter. The method for fabricating a permanent magnet rotor involves providing a rotor support with an axis of rotation, where at least two poles are equipped with permanent magnets. A screen made from a highly conducting material is applied to the surface of the permanent magnets facing the stator of the electrical machine. This screen is applied galvanically, and an annular fiber-reinforced support is fitted on top. The rotor support consists of two partially conical parts that interact to prestress the rotor radially. His second patent, the DC feedback firing control circuit, is designed for semiconductor components of a converter circuit that converts direct current into three-phase current. This circuit measures rotor position and direct current, determining the commutation angle based on a model of the synchronous machine.
